DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example

[0032] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a stretcher cart for cardiovascular medicine, comprising a cart body 1, a universal wheel 2 is provided at the bottom of the cart body 1, a lifting mechanism 3 is provided on one side of the cart body 1, and a transport mechanism 4 is provided on one side of the lifting mechanism 3;

[0033] like Figure 3 、 Figure 4 and Figure 5As shown, the lifting mechanism 3 includes a first pulley group 31, a second pulley group 32 and a crank handle 308. The first pulley group 31 and the second pulley group 32 are symmetrically arranged with the trolley body 1 as the center. The first pulley group 31 and the second pulley group 32 both include a roller 301, a cable 302, a roller 303, a first rotating shaft 304, a worm gear 305, a second rotating shaft 306 and a worm 307. The roller 301 is movably mounted on one side of the trolley body 1, a cable 302 is provided on one side of the roller 301, the cable 302 is fixedly connected to one side of the roller 303, the roller 303 is fixedly mounted on one side of the first rotating shaft 304, a worm gear 305 is fixedly mounted on one side of the first rotating shaft 304, a worm gear 307 is meshed with one side of the worm gear 305, the worm gear 307 is fixedly mounted on one side of the second rotating shaft 306, and a crank handle 308 is fixedly mounted on one side of the second rotating shaft 306.

[0034] The lifting mechanism 3 also includes a bearing seat 309, an outer shell 310, a bearing ring 311, an anti-pull cloth 312 and a steel plate 313. The bearing seat 309 is fixedly installed on one side of the cart body 1, the outer shell 310 is fixedly installed on one side of the cart body 1, a bearing ring 311 is provided on one side of the outer shell 310, the anti-pull cloth 312 is movably installed on one side of the roller 301, and steel plates 313 are fixedly installed on both sides of the anti-pull cloth 312.

[0035] The second rotating shaft 306 is movably mounted on one side of the bearing seat 309 , the second rotating shaft 306 is movably mounted on one side of the bearing ring 311 , and the crank handle 308 is movably mounted on one side of the housing 310 .

[0036] The cable 302 is fixedly mounted on the bottom of the steel plate 313 , and the first rotating shaft 304 is movably mounted on one side of the cart body 1 .

[0037] It needs to be further explained that: when the transport mechanism 4 needs to be pulled from a low place to a high place, the second rotating shaft 306 is driven to rotate by manually turning the crank handle 308, and further drives the worm 307 and the worm wheel 305 to engage and transmit, thereby driving the first rotating shaft 304 and the roller 303 to rotate. When the roller 303 rotates, the cable 302 is wrapped around the roller 303. At this time, the steel plate 313 connected to the top of the cable 302 drives the anti-pull cloth 312 to bypass the roller 301 and move toward the first rotating shaft 304, thereby driving the transport mechanism 4 at the bottom of the anti-pull cloth 312 to move upward.

[0038] like Figure 5 、 Figure 6 and Figure 7As shown, the transport mechanism 4 includes a base plate 401, a baffle 402, a pull-out plate 403, a column 404, a turntable 405, a first slide 406 and a second slide 407. The base plate 401 is fixedly installed on the bottom of the anti-pull cloth 312, a baffle 402 is fixedly installed on one side of the base plate 401, a pull-out plate 403 is movably installed on one side of the baffle 402, a column 404 is fixedly installed on the bottom of the pull-out plate 403, a turntable 405 is movably installed on the bottom of the column 404, a first slide 406 is provided inside the base plate 401, and a second slide 407 is provided at the bottom of the first slide 406.

[0039] The transport mechanism 4 also includes a top plate 408, a slide rod 409, a composite plate 410 and a block 411. The top plate 408 is fixedly mounted on the top of the pull-out plate 403, the slide rod 409 is fixedly mounted on one side of the pull-out plate 403, one side of the slide rod 409 is fixedly connected to the composite plate 410, and the bottom of the slide rod 409 is fixedly connected to the block 411.

[0040] The slide bar 409 is movably mounted inside the first slide groove 406 , the clamping block 411 is movably connected to the inside of the second slide groove 407 , and the slide bar 409 is movably sleeved on one side of the baffle 402 .

[0041] What needs to be further explained is that: when a patient on the ground needs to be lifted onto the transport mechanism 4, the pull-out plate 403 is manually pulled out until the block 411 at the bottom of the slide bar 409 contacts the baffle 402. At this time, the slide bar 409 is unable to move forward due to resistance. During the movement of the pull-out plate 403, the rotating wheel 405 and the column 404 serve as support points for the pull-out plate 403. When the slide bar 409 on one side of the pull-out plate 403 is completely moved out of the bottom plate 401, the patient is lifted onto the top plate 408 on the top of the pull-out plate 403, and then the pull-out plate 403 is reset.

[0042] The working principle and usage process of the present invention: During the use of the present invention, when a stretcher cart for cardiovascular medicine is used, first, the patient on the ground is lifted onto the transport mechanism 4, and the pull-out plate 403 is manually pulled out until the block 411 at the bottom of the slide bar 409 contacts the baffle 402. At this time, the slide bar 409 is unable to move forward due to resistance. During the movement of the pull-out plate 403, the rotating wheel 405 and the column 404 serve as support points for the pull-out plate 403. When the slide bar 409 on one side of the pull-out plate 403 is completely moved out of the bottom plate 401, the patient is lifted to the top plate 408 on the top of the pull-out plate 403, and then the pull-out plate 403 is reset.

[0043] Next, when the transport mechanism 4 needs to be pulled up from a low place to a high place, the crank handle 308 is manually turned to drive the second rotating shaft 306 to rotate, and further drive the worm 307 and the worm wheel 305 to engage and transmit, thereby driving the first rotating shaft 304 and the roller 303 to rotate. When the roller 303 rotates, the cable 302 is wrapped around the roller 303. At this time, the steel plate 313 connected to the top of the cable 302 drives the anti-pull cloth 312 to bypass the roller 301 and move toward the first rotating shaft 304, thereby driving the transport mechanism 4 at the bottom of the anti-pull cloth 312 to move upward.

[0044] Finally, when the transport mechanism 4 is lifted to the top of the cart body 1, the card plate on one side of the cart body 1 will limit the movement of the pull-out plate 403, preventing the slide bar 409 on one side of the pull-out plate 403 from sliding out of the bottom plate 401 during the process of transferring the patient.

[0045] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
